Ability to use multiple instances

In my opinion, this is a very important feature provided by localForage and missing in ionic-storage.

With this feature, we can iterate on different data stores, (e.g. messages in conversations)

e.g.

let myConversation = localForage.createInstance({name: 'conversationId'});
myConfersation.iterate((v, k) => ...);

Hi Max. I think you misunderstood the issue.

The problem is not forEach support, but multiple instances.

In ionic storage, there is no multiple instances support so if we have a list of items of different data models, we have to iterate through every item in the whole database.

Let’s say we have 100 different conversations and we try to iterate messages in one conversation, we have to iterate through all the messages in all the conversations if we do not have multiple instances.

But if we just create new instance for that particular conversation, we can just iterate through these messages.

Any news on this? The solution from @ahoebeke works but I think it would be cleaner to have a function for this wrapper that uses createInstance from localForage. That would be really great and shouldn’t be much work I guess?
